This would be great! C++ API exposes it through MessageEvent and Python API on 
the message header itself. Rosjava, AFAIK, does not provide any option for 
doing this.

Due to this issue, interoperability is not asured when using different APIs on 
a project like the one I am working on, where an indeterminate number of 
GPS-equipped robots are spawned on real time. This way, C++ and Python robots 
can tell which fix belongs to which robot, but rosjava based ones can't, unless 
we implement our own modified version of sensor_msgs/NavSatFix message with 
CallerID information.
